A PowerShell function for getting user metadata. See help for more details.

PSWho.ps1

Function Get-PSWho {
  <#
  .SYNOPSIS
  Get PowerShell user summary information
  
  .DESCRIPTION
  This command will provide a summary of relevant information for the current 
  user in a PowerShell session. You might use this to troubleshoot an end-user
  problem running a script or command. The default behavior is to write an 
  object to the pipeline, but you can use the -AsString parameter to force the
  command to write a string. This makes it easier to use in your scripts with
  Write-Verbose.
  
  .PARAMETER AsString
  Write the summary object as a string.
